Law of physics can be demonstrated by collection of individual protein molecules

Experiments by biochemists at the University of California, Davis show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules -- specifically, a protein that unwinds DNA. The work will be published online by the journal Nature on July 14.

Accumulation of plaques in brain may serve as powerful biomarker for early detection of cognitive decline

The trajectory of amyloid plaque buildup-clumps of abnormal proteins in the brain linked to Alzheimer's disease-may serve as a more powerful biomarker for early detection of cognitive decline rather than using the total amount to gauge risk, researchers from Penn Medicine's Department of Radiology suggest in a new study published online July 15 in Neurobiology of Aging.

Researchers identify genes that allow animal hepatitis E virus strains to infect humans

X.J. Meng, a University Distinguished Professor at Virginia Tech and a virologist at the Virginia-Maryland Regional College of Veterinary Medicine, has received a four-year, nearly $1.6 million grant from the National Institutes of Health to better understand the genetic elements that allow hepatitis E virus to transfer from animals to people.

Study shows link between FTO, ghrelin and impaired brain food-cue responsivity

Individuals carrying the "obesity-risk" allele of the fat mass and obesity associated gene, FTO, are prone to obesity and obesity related eating behaviors such as increased food consumption, preference for high fat foods and lack of satiation after eating.

Excess fat in liver, muscle tissue and blood may increase risk of bone loss

Excess fat around the belly has recently been identified as a risk factor for bone loss. Now, a new study has determined that excess liver and muscle fat also may be detrimental to bone.

USC study shows missing brain protein may be responsible for severe over-worry and fear

A little bit of learned fear is a good thing, keeping us from making risky, stupid decisions or falling over and over again into the same trap. But new research from neuroscientists and molecular biologists at USC shows that a missing brain protein may be the culprit in cases of severe over-worry, where the fear perseveres even when there's nothing of which to be afraid.

Researchers uncover role of IKACh in pacemaker activity and heart rate regulation

Researchers have uncovered a previously unknown role for the acetylcholine-activated inward-rectifying potassium current (IKACh) in cardiac pacemaker activity and heart rate regulation, according to a study in The Journal of General Physiology.

Cranberry consumption may prevent chronic infections

Consuming cranberry products has been anecdotally associated with prevention of urinary tract infections (UTIs) for over 100 years. But is this popular belief a myth, or scientific fact?

Study shows flavonoid-based nutritional supplements can affect endocrine system

Plant-based diets are healthy. Plants are high in flavonoids. So flavonoids are healthy. At least that's the reasoning of many manufacturers of flavonoid-based nutritional supplements.

Researchers discover that JNK3 expression is downregulated at early stages of traumatic brain injury

Increasing evidence has revealed that the activation of the JNK pathway participates in apoptosis of nerve cells and neurological function recovery after traumatic brain injury.

Scientists discover how BRCA1 gene mutations predispose women to breast and ovarian cancers

Scientists led by Drs. Mona Gauthier and Tak Mak at The Campbell Family Institute for Breast Cancer Research at the Princess Margaret Cancer Centre have solved a key piece in the puzzle of how BRCA1 gene mutations specifically predispose women to breast and ovarian cancers.

Vitamin D supplementation can improve patient's immunological status

Vitamin D influences many other physiological processes, including muscle function, cardiovascular homeostasis, nerve function, and immune response. Furthermore, accumulated evidence suggests that vitamin D also mediates the immune system response to infection. Infections are very common in patients from neurosurgical intensive care unit.

Proteins involved in immunity produce cancer-causing DNA mutations, study finds

A set of proteins involved in the body's natural defenses produces a large number of mutations in human DNA, according to a study led by researchers at the National Institutes of Health. The findings suggest that these naturally produced mutations are just as powerful as known cancer-causing agents in producing tumors.

Researchers use EEG signals for artifact suppression and brain wave extraction

Electroencephalography is a test to measure the electrical activity of the brain generated by scalp surface after being picked up by metal electrodes and conductive media. Proper classification of electroencephalography data is the main task in electroencephalography based brain computer interface.

Scientists discover new details of biochemical interactions necessary for cell division

Building on earlier work exploring the complex choreography by which intricate cellular proteins interact with and copy DNA prior to cell division, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and collaborators have captured a key step-molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target.
